Daniel Marjamäki 4391f0880f Tokenizer: Add special tokenize method for the Preprocessor with only basic simplifications 2013-01-27 17:58:54 +01:00

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

Edoardo Prezioso 4c73c29cdd Revert partially the previous commit:
The two formulas are true iff 2n = 2 <=> n = 1.
2013-01-05 17:31:08 +01:00
Edoardo Prezioso 1c0c0471df Simplify some generalized math formulas:
Now the 'sin^2+cos^2=1' and the 'sinh^2-cosh^2=-1' code can handle, for example: sin^4+cos^4=1, sinh^10-cosh^10=-1.
Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.
2013-01-04 13:06:09 +01:00
Edoardo Prezioso 5485e6866f Fixed wrong tokenization of some math formulas:
The two formulas: sin^2+cos^2 = 1 and sinh^2-cosh^2 = -1 are true iff the two arguments are the same.

Edoardo Prezioso f3029ce6bb Fixed a bug in Tokenizer::simplifyKnownVariables.
When we find constant variables, check if there's a usage of its reference in the code (for example: don't simplify 'f(&x)' to 'f(&100)').

Edoardo Prezioso 1951d1cdc5 Tokenizer: improve the new 'skipTernaryOp' function by supporting GCC '{(var|num;)}' statement expression extension; improve 'Tokenizer::simplifyQuestionMark' by supporting simplification with 'case' before ternary operation, using skipTernaryOp to get colon and, most importantly, supporting indented '?:' operations. 2012-10-13 02:32:43 +02:00
